I believe there's actually so much combat nowadays in games thaz ethics are - apart from a cmisty "reputation" thrown over board altogether.

These games nowaday don't teach ethics. They instead teach how to be quick and kill before your opponents can rise their hands against you.

I believe these games teach the wrong thing.

And no, before the first one sass "but this is only a game" : You learn anyway. Like I learned while playing X-Wing that putting the joystick too much on one side makes you crash into the next starship.
I became a much more careful car driver, after learning that.

You learn things in games anyway. That's what game partially are for !
